The appearance on the screen of a Xiaomi, Redmi or POCO smartphone logo with the image of a hare fixing an android often takes the user by surprise. This mode is called Fastboot, and it is primarily designed for developers and service centers to deep-flash the device. However, for the average phone owner, getting into this menu means not being able to make calls, use instant messengers or just go online.
The situation may seem critical, but in most cases, the system failure is temporary and does not require complex intervention. 90% of the time, the cause is accidental clamping of the key combination in the pocket or case. There are several proven methods to force the gadget to restart and return to normal operation of the operating system MIUI or HyperOS.
In this article, we will discuss in detail the algorithms of actions for different scenarios, from a simple restart to using specialized software on a computer. It is important to understand that your data is usually stored unless you reset to factory settings. Below are step-by-step instructions that will help you quickly solve the problem.
Reasons for spontaneous transition to Fastboot mode
To effectively fix the problem, you first need to understand the source of the problem: Fastboot mode is activated on Xiaomi devices when booting, if the system detects conditions, most often due to mechanical impact on the device body during the on-off.
One of the most common causes is a malfunction or design feature of physical buttons. If the Volume Down button is stuck, oxidized, or simply pressed with a case, the phone reads it as a command to enter the engineering menu when it is turned on, and the cause may also be damage to the button plume after falling.
Another important factor is software failures when updating the system: If a file write error or power interruption occurs during the installation of a new version of MIUI, the bootloader may not find a valid operating system and go into command standby mode, and in rare cases, a poor-quality application that conflicts with system processes becomes the culprit.
โ ๏ธ Warning: If the phone itself periodically reboots into the Fastboot without you, this may indicate battery wear.
It's also worth considering the human factor. Many users accidentally pinch the button combination in their bag or jeans pocket. Because when switched off, the long-term "Loudness Down" + "Power" clamping is the trigger to enter this mode, the phone switches to it the next time you try to turn on.
Method 1: Forced button reboot
The simplest and safest method that works in the vast majority of cases is a forced restart, which requires no connection to a computer or additional tools, and the essence of the method is to emulate the battery extraction, which causes the power controller to completely reset the system state.
To do this, you'll need to hold the Power button for a long time. A standard short press here won't work, because in Fastboot mode, the system ignores the usual signals. You'll need to hold the key for about 10-15 seconds until the screen goes out.
Once the screen goes out, release the button immediately. If it goes well, the device vibrates, and the Mi or Redmi logo will appear on the screen, marking the start of a normal boot. If the phone is back on the menu with a hare, repeat the procedure, but this time try to press the button a little harder to eliminate the effect of sticking.
โ๏ธ Reboot algorithm
Some models, especially those with a plastic body or specific layout, may require the simultaneous pressing of the โLoudness upโ and โPowerโ buttons, a method less common for exiting Fastboot, but on older Xiaomi models it is sometimes more effective.
Method 2: Using the ADB command on a computer
If physical buttons fail to respond or are damaged, a software method comes to the rescue, and you will need a computer (Windows, macOS or Linux) to implement it, which is serviceable. USB-cable and installed set of drivers ADB (Android Debug Bridge is considered a more โcleanโ method, as it does not depend on the state of the phoneโs mechanics.
First, you need to prepare the work environment. Download Platform-tools from the official Android developer site. Unpack the archive into the root folder of the disk, for example, in C:\adb, so that the path is short. Then connect the phone to the PC with a cable. In Fastboot mode, drivers are usually installed automatically, but may require manual installation through Device Manager.
Open the command prompt (CMD) or PowerShell on behalf of the administrator. Go to the tool folder by entering the command cd C:\adb. To make sure the computer sees the phone, type in fastboot devices. If you see the serial number of the device in response, the connection is established.
fastboot rebootOnce you input this command, the phone should immediately restart as normal, which is the most reliable way if the power button is physically broken, but if the drivers are not properly installed, the system may not recognize the device and the command will not execute.
What if the ADB canโt see the phone?
Method 3: Method of battery discharge
When software methods are unavailable and the buttons don't work, the last option, albeit a long one, is complete discharge, which is based on the fact that at a critically low charge, the battery can't keep even the bootloader mode running, and the device shuts down.
Leave the phone with the Fastboot screen on until it is completely discharged and goes out.This can take anywhere from a few hours to a day, depending on the residual charge.
Once the screen is out, plug in the original charger. Let the phone lie on charge for 10 to 15 minutes, even if the screen doesn't light up right away. Then try turning it on in the usual way. Often after this cycle, the power controller resets the errors and the phone boots normally.
โ ๏ธ Warning: Do not leave a fully discharged lithium-ion battery in this state for a long time (weeks or months) and this can lead to a deep discharge and inability to charge further.
Diagnostics of physical damage to buttons
If the phone is constantly returning to Fastboot mode after each reboot, there is a high probability of mechanical failure. In Xiaomi devices, the Volume Down button is often responsible for entering this mode. Check the tactile sensation of pressing: the move should be clear, with a clear click.
If the button fails, crunches or does not return to its original position, the problem is solved only in the service center, in some cases, the gently tapping the case in the area of the buttons or purging with compressed air if dust or moisture gets inside.
It's also worth removing the protective case. Cheap or deformed cases can put constant pressure on the keys. Try turning on the phone without accessories. If the problem is gone, just replace the case with a better one.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone goes into Fastboot on its own. | Volume button sticking | Cleaning the button, replacing the plume |
| Reboot doesn't help. | Damage to system files | Flashing through MiFlash |
| The screen blinks and goes out. | Critical battery discharge | Long-term charge (30+ min) |
| The computer can't see the device. | No drivers or bad cable | Installation of drivers, replacement of cable |
Firmware of the device through the Mi Flash Tool
If none of the above methods worked, the bootloader or system partition may have been damaged, which would require a complete firmware reinstallation, using the official Mi Flash Tool utility and the downloaded firmware in.tgz (Fastboot ROM).
It is important to understand that this process is more complex and requires care. You will need to download the firmware for your model (model codes differ even for the same name, for example, Redmi Note 10 has different versions for the global market and China).
The process is like this: unpack the archive with the firmware, open the Mi Flash Tool, connect the phone in Fastboot mode, select the path to the firmware folder and click the "Flash" button. Select the "Clean all" option to avoid file conflicts.
โ ๏ธ Note: Fastbootโs firmware process completely removes all data from the device. Make sure you have a backup of important photos and contacts if the phone has any reaction before it hits this mode.

Using the original firmware and USB 3.0 cable significantly reduces the risk of errors when flashing and speeds up the process of writing data.
